I'm so lost. All these the threads about rooting and stuff and I don't understand. I followed all the video tuturials and picture tutorials for doing it and I keep getting the same error. E: Signature verification failed. I typed it into google and got everything from, maybe your zip file is named accidentally .zip.zip so just delete the extra .zip to you installed 2.1. You can't root without going back. Or youll have to falsh the 2.0.1 sbf. They also talk about some FAQ which I can't find and these terms like sbf and 2.0.1 and 2.1 and rooting without going back. What does this mean. I'm so confused. Help. Please. Thank you.
